In Tibetan religious literature, Jamgön Kongtrül's Treasury of Knowledge in ten books stands out as a unique, encyclopedic masterpiece embodying the entire range of Buddhist teachings as it was preserved in Tibet. The tantric path is often referred to as the indestructible way of secret mantra, the essence of which is the indestructible union of wisdom (the understanding of emptiness) and method (immutable great bliss). This volume sets forth the various systems that constitute this path, both those of the ancient tantra tradition and of the new tradition.

"The Treasury of Knowledge excellently presents the entire corpus of the sutra and mantra traditions from the paths of the common sciences all the way up to the uncommon Great Perfection or Atiyoga, which is the culmination of the nine vehicles." —H.H. Dudjom Rinpoche

"Jamgön Kongtrül Lodrö Tayé was one of the leading scholars of the nineteenth century.

Finally we might know what we are doing!" —Sarah Harding
